I have an 06 Ram 2500 SLT that did not come with fog lamps. I have found a full kit on eBay for $147 shipped that includes the lamps, bezels, harness, and switch but this will only work for trucks prewired for fog lamps. I know I am looking for a wire hanging on the driver side frame rail with a red lock clip on it but I found more than one and want to be sure one of these is it before I drop the cash on the kit.

Are one of these the wire that indicates my truck is pre-wired for fog lamps?

This one?


Or maybe this one?


I imagine someone whose truck came with factory fog lamps could probably go out and snap a photo of the wires directly connected to the back of there fog lamps attached to the bumper and it would probably answer my question.

Thanks!

Yeah the 2nd pic is what you plug into with your new wiring harness
that should be a short 6" wire w/a pigtail that will run down the front bumper to the passenger side fog.
Easy peasie lemon sqeezie.

Did you check behind the fog light holes for an oval two-pin connector? A lot of the trucks (especially SLT) without the fog lights are still wired all the way to where the bulb would go. You will, however, need to get the fog light option turned on in the computer before they will light up with the headlight switch.

Thanks guys. I'm going to go ahead and order it. I hear that it is a 50/50 chance that my computer needs to be reprogramed so here's hoping I don't!

If your truck did not come from the factory with fog lights installed, there is a 100% chance you will need to have the option enabled by a dealer's StarScan tool.

Mine did not come with factory fogs. bought the kits from the dealer 1hr later fog lights. Did not have to reprogram pcm.

Didn't have to go to the dealer when I put mine in.. Guess i'm just one of the lucky ones.

Both of you have 2005-prior models. I'm pretty certain it's only for the 2006+ tipm controlled years. There is no provision to control the fogs in the older models. It's circuitry within the tipm that needs to be activated.

OP, please post back and let us know how you made out.

Sorry, should have been more specific, I was replying specifically to the OP. You are right, I was referring to the '06+ models. They seem to be pre-wired for almost everything, but adding a component that didn't come from the factory almost always requires it to be enabled in the computer. If I ever find an '09+ leather interior, I'll find out if those heaters are handled by the computer too.

Sorry I took forever to reply. I plugged in the factory kit and the fogs worked perfectly. No need to reprogram on my 06 2500 to get them to work. I love plug-n-play!
